You can declare your stored procedures using

CREATE PROCEDURE [dbo].YourStoredProcedure
    @Start DATETIME, 
    @END   DATETIME
AS

Then you can get rid of the code needed to cast from string

In order to get the results mapped as a c# object, you need to use SqlQuery or FromSql depending on the version of Entity Framework that you are using

Entity Framework 6

var result = dbContext.Bar.SqlQuery("EXEC YourStoredProcedure").ToList();

To pass a parameter, you woild do something like

var result = dbContext.Bar.SqlQuery("EXEC YourStoredProcedure @SomeParameter", 
             new SqlParameter("@SomeParameter", TheParameterValue)).ToList();

And for Entity Framework Core 2

var result = dbContext.Bar
.FromSql("EXEC YourStoredProcedure")
.ToList();

Where Bar is your C# object declared as a property with type DbSet in your dbContext class

Based on your output you should create a C# object similar to

public class Bar
{
     public datetime DateRecSlash { get; set; }
     public int CodeMarz { get; set; }
}
